I don't understand why Robert Tagliapietra and Jeffrey Costello aren't a perennial Halloween staple — maybe because they're already kind of in dandy lumberjack costumes, and that many levels of costumes are just confusingly pomo.

Christian Siriano, after-dark.

Aurelie Claudel, in the kind of effortless Franco-chic that's so hard to replicate.
